Howe Caverns is a premier natural attraction, a living, limestone cave, carved by an underground river over the course of 6 million years, located 156-feet below the earth's surface. An Schoharie County, N.Y. farmer discovered the caverns more than 160 years ago. Formed in 1927, Howe Caverns incorporated, a public company owned by shareholders, opened the caverns to the public on Memorial Day weekend of 1929.
Definition of 'Volatility'. Definition: It is a rate at which the price of a security increases or decreases for a given set of returns. Volatility is measured by calculating the standard deviation of the annualized returns over a given period of time. It shows the range to which the price of a security may increase or decrease.
From Wikipedia, the free encyclopedia. In financial mathematics, the implied volatility of an option contract is that value of the volatility of the underlying instrument which, when input in an option pricing model (such as BlackâScholes) will return a theoretical value equal to the current market price of the option.
